Experience the pinnacle of FPV racing frame technology with the Five33 LightSwitch V2 Ultra. This is not just an iteration; it’s a revolution. Engineered for an unparalleled competitive edge, the LightSwitch Ultra was crowned a winner at the French National Championship even before its official release. Featuring the innovative LightSwitch V2 Spine System for extraordinary stiffness and a jaw-dropping sub-50-gram weight, this frame redefines agility and strength for the serious FPV drone racer.

A Championship-Winning Design As explained by the Five33 team, the LightSwitch Ultra was engineered with a singular focus: to create the lightest possible racing frame without compromising on stiffness, durability, or component compatibility. By integrating the proven spine plate technique from the LightSwitch V2, the Ultra achieves incredible rigidity and Black Box performance, giving pilots the confidence to push their limits on the track.

Stiffness Without the Weight The innovative LightSwitch Spine System is the key to the Ultra’s incredible performance. This design utilizes longitudinal carbon fiber stiffeners to create a rigid core down the center of the frame, providing exceptional stiffness and preventing arm flex during hard cornering. This allows the rest of the frame to be machined for maximum weight savings without sacrificing a locked-in feel.

Built For Racers, By Racers. Every detail of the LightSwitch Ultra is designed for the competitive pilot. The unique motor mounting platform simplifies the use of arm braces, and the frame is compatible with a huge variety of custom 3D printed camera mounts. Most importantly, the arm kit includes five arms, so you have a spare ready to go for quick trackside repairs, keeping you in the race.
